The numeral 15 refers to two longitudinallyextending angle bars which areV secured in spaced relation by two metalstraps 16 riveted to the angle bars and adapted to lie one Vateitherside of the cross bar 13. Then these parts are in the relation describedand shown the angle bars 15 are supported upon the plate'9 and are heldagainst lateral displacement by the lupturned ends 14: of the bar' 13and are -held against angular movement relative to the plate by theengagement ofthe bar 16 with theV straps 13.v The horizontal flanges 17of the angle bars 15 are piercedA adjacent each end by apertures whichare adaptedy to receive downwardly projecting studs V18 secured to thefloor plates 19 and 20 and these studs 18 are transversely pierced v bysuitable apertures adapted to receive the keys v 21 by which thepartsare secured in place. When thus assembled the angle bars 15 andfloorplates 19 and 20 constitute a f truckbody adapted to'receive andsupport a coal cutting machiney of the vwell known shortwall type. Forconvenience in loading or unloading the coal cutting'machine upon the`truck its'body may be rockedV upon the cross bar l13 totilt the anglelbarsk15 into contact with the mine floor, and it may be turned workingfacel in thek minefroom to the carsV aboutthe stud 11 to the preferredangularV relation with the longitudinallines of the conveyor.

- In Fig. 5 ofthe drawing I have illustrated a typical' installationcomprising a mine entry 22 and a mine room 23. In the entry there isprovided the customary track 24V along which travel the mine cars bywhich dislodged coal is transported from the mine. Extending from theentry longitudinally of the mine room is aconvey'or 25 of the well knownchain andescraper type lby which the dislodged vcoal may be transportedfromthe I 'positioned' up'on the track 24`in the entry.

The principal mining operations occur upon the longface 26 of the room23 which ex-` tends parallel with the conveyor 25, and'suit- Vablegathering mechanism, not shown in the drawings', is commonly employed togather thedislodged coal from the ioor of the mine `and, transferi't tothe conveyor 25 to 'be loaded into the cars'uponthe mine track. Afterall Vofthe dislodged coal hasbeen removed from the room 23 a suitablecoal cutting mechanism indicated at `27 in `Figf5of the drawing, will bebrought into the room and operated to lundercut the coal along the face26, beginning at the inner end of the face and terminating at the outerend adjacent the entry. Coal cutting machines such as are herecontemplated are provided with trucks 28 adapted to" travel along thetracks of the mine to transport the machine from one working place toanother. Since the coal is delivered `to the mine cars in the entries nobranch tracks are laid into the rooms, and this necessitates thedischarge ofthe mining machine: 27 from the truck 28 at a point in theentry' adjacent the mouth of the room. ln order that the mining machine27 may be conveniently and expeditiously transferred to the j point ofbeginning the undercutting operat-ion in the mine room, my improvedtruck 29 may be assembled upon lthe conveyor 25, in the manner abovedescribed, its body placed in longitudinal alignment with the body ofthe truck 28 upon the mine track and the mining machine 27 transferredfrom the truck 28 to the truck 29. The conveyor chain 4 `may then beactuated to propel the truck 29 to the place of beginning the cuttingoperation where the mining machine 27 may be unloaded in the mannerwhich is well understood by those skilled in, the art. After thecompletion of the cutting operation the truck 29 may be movedtoproximity with the mining machine 27, and the machine may be thenreloaded-onto the truck and from it transferred tothe truck 28 in themine entry, to be transported to thenext working place. After thecompletion of the cutting operation and the removal of the miningmachine from the truck 29, said truck may be disassembled therebyleaving the conveyor trough unobstructedforthe transfer of broken coalto the minecars as above described.
